Snell's law, or the law of refraction, describes the relationship between the angles of incidence θ₁ and refraction θ₂ and the refractive indices (n₁, n₂) of two media: n₁sin(θ₁) = n₂sin(θ₂). The law of refraction allows us to predict the amount of bend when light travels from one medium to another.

The refractive index of oil is the ratio of the speed of light in a vacuum to the speed of light in oil. It is a measure of how much light is bent when it passes through oil. The higher the refractive index, the more light is bent. Oil has a high refractive index because its molecules are close together and interact with light strongly.

Definition: INDEX OF REFRACTION. We define the index of refraction (n) of a material to be [n = frac{c}{v}, label{index}] where (v) is the observed speed of light in the material. Since the speed of light is always less than (c) in matter and equals (c) only in a vacuum, the index of refraction is always greater than or equal to one.

Refractive Index is a property of any material which is used to define the ratio between the speed of light in a medium to the speed in a vacuum. It is denoted by the symbol μ. When travelling in a medium other than the vacuum light particles are absorbed and re-emit by the medium which slows down the speed of light.
